If someone (including the OP) wants to attempt to create some type of stick-on lettering, all you need to do to get your graphics ready is hand one of those readily-available copies of the logo over to a graphics designer and they can whip this out in 15 minutes or less. You don't need a font. According to my caliper the GY lettering is 2" high and the Eagle is 1.5". This being measured with the sidewall bulge. Best course of action would be to measure a tire not mounted.
